The Central Market Agency (CMA) keeps a record of which customers are served by which Licensed Provider.
The CMA calculate the wholesale charges payable to us for each supply point. Details of the process for calculating wholesale charges can be found on the CMA website.
The CMA publishes provisional and reconciliation settlement reports that we use to calculate our charges. We calculate the payments due from, or to, each Licensed Provider. We will then issue invoices and reconciliation statements accordingly. Payment terms can be found in the Wholesale Services Agreement.
